Clock synchronization
(time synchronization equipment, timing system, Beidou network clock server) is a new generation of synchronous timing equipment independently developed by Jinan Weishang Electronics Co., Ltd., using Bus-type architecture, by replacing the input card board, the device can be flexibly configured between the main clock and the extended clock, realizing multiple applications of a single device. The product is powerful and realizes multiple functions such as intelligent error correction and input soft switching. Optional Beidou first-generation and second-generation timing boards developed by Weishang Company can achieve the highest timing accuracy. It is widely used in electric power, communications, finance, telemedicine, computer and other industries to meet the time requirements of different network applications.
The product adopts modular design and supports multiple time signal outputs such as B,,,,,, and messages. According to the different signal output level characteristics or types, it is divided into eight types of signal output cards, R/, empty contact, R AC B code, and optical fiber, which can meet the various needs of current users.
Clock synchronization
Features
Intelligent error correction to avoid packet loss or packet errors caused by time source failure
When the input source is switched, the output is not interrupted, achieving soft switching
Applying high-precision, if the input source is temporarily interrupted, the high-precision output signal can still be maintained
High-performance crystal oscillator servo algorithm improves the retention performance of the output signal
Adopting technology, greatly improving the network performance Processing power and timing accuracy (can reach grade 1)
Application technology can handle instantaneous large traffic requests
When the input time source enters the free running state (unavailable), it automatically switches to another input source to form Protection
Various signal output settings of the user board are flexible, and the output card board and the port are completely isolated
It has a delay compensation function unique to the main time server, further improving time accuracy
Compatible with non- 3 input sources, output perfectly supports 3 protocols
The status of multiple input sources can be set at all times, and the priority can be set
A single device supports multiple message outputs at the same time to meet the various needs of users
